1-2-1. Establishment of WiFi Communication

First, using FIG. 4, a description is made to operations related to establishment of WiFi communication between the digital camera 100 and the smart phone 200. FIG. 4 is a sequence diagram regarding operations of connecting the digital camera 100 and the smart phone 200.

When the smart phone 200 is brought into touch with the digital camera 100 (S310), the controller 225 of the smart phone 200 reads connection information (SSID, WEP key) necessary for connecting with the digital camera 100, from the controller 135 of the digital camera 100 via the NFC tag 160 and the NFC reader/writer 240 (S310). When reading the connection information, the controller 225 of the smart phone 200 sets the read connection information in the smart phone 200 (S320). Hence the controller 225 of the smart phone 200 can identify the WiFi module 155 of the digital camera 100 which the smart phone 200 communicates with, and can decode a code for communicating with the identified WiFi module 155 of the digital camera 100. Hence, the WiFi module 235 of the smart phone 200 and the WiFi module 155 of the digital camera 100 can establish WiFi communication (S330).

After WiFi communication is established as thus described, when the smart phone 200 is brought into touch with the digital camera 100 in a state where a predetermined application is being activated in the smart phone 200, a remote control of the digital camera 100 becomes possible from the smart phone 200. At this time, a user interface screen for remote control, which is displayed on the smart phone 200, is selected in accordance with an operation mode of the digital camera 100. Operations of displaying the user interface screen on the smart phone 200 are described below.

1-2-2. Display of User Interface Screen for Shooting Mode

FIG. 5 is a flowchart for operations of displaying a user interface screen for shooting mode on the smart phone 200 according to the first embodiment. Using FIG. 5, a description is given to an operation of the smart phone 200 selecting and displaying a user interface screen in accordance with information regarding an operation mode setting which is read from the digital camera 100. It is assumed that the establishment of WiFi communication described in FIG. 4 is completed before the following operation of displaying the screen.

First, the user turns on a power supply of the digital camera 100, and thereafter operates a mode dial of the digital camera 100 to set the digital camera 100 in a shooting mode (S400). When set in the shooting mode, the digital camera 100 captures a subject image formed via the optical system 110, by means of the CMOS image sensor 115, and starts generating of captured data. The image processor 120 performs a variety of processes on the captured data to generate image data. The liquid crystal display monitor 130 displays a through image based on successively generated image data.

Further, the user operates the touch panel 210 of the smart phone 200 to activate application software. That is, the controller 225 of the smart phone 200 activates application software in accordance with the user's operation (S410). The application software is application software for allowing remote control of the digital camera 100 by the smart phone 200. By activating the application software, the smart phone 200 gets prepared for remote control of the digital camera 100.

Subsequently, the user brings the digital camera 100 and the smart phone 200 into touch with each other (S420). By this touch operation, the NFC reader/writer 240 of the smart phone 200 reads setting information regarding the operation mode of the digital camera 100 from the NFC tag 160 of the digital camera 100. Since the digital camera 100 is set in the shooting mode, the NFC reader/writer 240 of the smart phone 200 reads setting information indicating that the setting is the shooting mode, from the NFC tag 160 of the digital camera 100 (S430).

Subsequently, the controller 135 of the digital camera 100 transfers a through image (shot image) based on the image data which is successively generated by the CMOS image sensor 115, to the smart phone 200 via the WiFi module 155 and the WiFi module 235 (S440).

Thereafter, upon receipt of the setting information indicating that the shooting mode is set, which is read in Step S430, the controller 225 of the smart phone 200 reads data of a user interface (UI) screen for shooting-mode from the memory in the smart phone 200. The smart phone 200 has a correspondence table between the operation mode and the user interface screen, as shown in FIG. 6. By referring to the correspondence table shown in FIG. 6, the controller 225 of the smart phone 200 can select user interface screen data corresponding to the operation mode of the digital camera 100.

The controller 225 of the smart phone 200 superimposes an image indicated by data of user interface screen for shooting-mode on the through image (shot image) acquired in Step S440, to be displayed on the liquid crystal display monitor 215 (S450).

FIG. 7 is a view explaining a user interface screen for shooting mode. The liquid crystal display monitor 215 of the smart phone 200 displays the user interface screen for shooting mode, as shown in FIG. 7. The user interface screen for shooting mode includes a display region 2000 and operating instruction buttons 2010 as shown in FIG. 7. The display region 2000 is a region for displaying the through image (shot image) acquired from the digital camera 100 in Step S440. The operating instruction buttons 2010 are buttons each for sending an instruction for operation to the digital camera 100. The user operates the touch panel 210 to operate any of the operating instruction buttons 2010 displayed on the liquid crystal display monitor 215. Upon receipt of this operation, the controller 225 of the smart phone 200 transmits the instruction for operation to the digital camera 100 via the WiFi module 235 and the WiFi module 155.

Upon receipt of the instruction for operation from the smart phone 200, the controller 135 of the digital camera 100 changes a shooting condition. The controller 135 of the digital camera 100 then transfers a through image (shot image) shot based on the shooting condition after the change of the shooting condition, to the smart phone 200 via the WiFi module 155 and the WiFi module 235.

As thus described, when reading the setting information indicative of the setting (shooting mode) of the digital camera 100, the smart phone 200 selects a user interface screen for shooting mode corresponding to the setting information. Accordingly, when the digital camera is in the shooting mode, the smart phone can be automatically switched to the shooting mode without the user manually making a setting.

1-2-3. Display of User Interface Screen for Playback Mode

FIG. 8 is a flowchart showing operations of displaying a user interface screen for playback mode in the smart phone 200 according to the first embodiment. The smart phone 200 displays the user interface screen for playback mode in accordance with information regarding a playback mode setting, which is read from the digital camera 100. It should be noted that the establishment of WiFi communication described in FIG. 4 is assumed to be completed before the operations shown in FIG. 8.

The operations regarding the playback mode from Step S500 to Step S550 in FIG. 8 are basically similar to the operations regarding the shooting mode from Step S400 to Step S450 in FIG. 6, except for the following matters.

(1) The current setting in the digital camera 100 is the “playback mode”, and setting information indicates the playback mode.

(2) Image data recorded in the memory card inserted in the digital camera 100 is transferred to the smart phone 200.

(3) Upon receipt of the setting information read in Step S530, the user interface screen for playback mode is displayed.

FIGS. 9 and 10 show examples of the user interface screen for playback mode user interface screen. FIG. 9 is a view showing a user interface screen for a single image playback mode. FIG. 10 is a view showing a user interface screen for multi-image playback mode. A single image playback mode is a playback mode for displaying only one image. A multi-image playback mode is a playback mode for simultaneously displaying a plurality of images. Based on the setting information acquired in Step S530, the smart phone 200 displays a user interface screen for the corresponding playback mode in accordance with whether the current setting in the digital camera 100 is the single image playback mode or the multi-image playback mode.

As thus described, the smart phone 200 according to the first embodiment includes the liquid crystal display monitor 130, the NFC reader/writer 240 for reading information regarding the current operation mode from the digital camera 100 having a plurality of operation modes, and the controller 225 for switching the user interface screen to be displayed on the liquid crystal display monitor 130 in accordance with information regarding the operation mode read by the NFC reader/writer 240.

That is, the smart phone 200 reads information regarding the operation mode (shooting mode/playback mode) from the digital camera 100 and decides, based on the read information, the screen for shooting-mode or the screen for playback mode, as the screen to be displayed on the liquid crystal display monitor 215 of the smart phone 200. At this time, the information regarding the current mode setting in the digital camera 100 (information regarding the shooting mode/playback mode) serves as information regarding the shooting mode/playback mode which is to be read by the smart phone 200.

Accordingly, when the digital camera 100 is in the shooting mode, the smart phone 200 can be automatically switched to the shooting mode without the user manually setting the smart phone 200 in the shooting mode. This can facilitate the user to set the smart phone 200 in the shooting mode, and can further facilitate the user to perform a remote control of the digital camera 100 for shooting an image by means of the smart phone 200.

The smart phone 200 according to a second embodiment extracts an image related to attribute information (additional information) of a specific image from among images recorded in the flash memory 245 of the smart phone 200, based on the attribute information read from the digital camera 100. Then, the smart phone 200 displays a result of the extracted image on the liquid crystal display monitor 130. It is thereby possible to instantly find an image highly related to an image being displayed on the touched digital camera 100 out of the images recorded in the flash memory 245 of the smart phone 200.

Configurations of the digital camera 100 and the smart phone 200 according to the second embodiment are similar to those described in the first embodiment, and hence a detailed description thereof is omitted. The same constitutional elements as those in the first embodiment are described with the same reference numerals (the same applies to the following embodiments).

Hereinafter, operations of the digital camera 100 and the smart phone 200 according to the second embodiment are described.

(1) Case of Using Image Identifier as Attribute Information

FIG. 11 is a flowchart of an operation in the case of using an image identifier as attribute information. The user of the digital camera 100 selects image data to be searched from the memory in the smart phone 200 out of the image data recorded in the memory card 145, and displays an image indicated by the selected image data on the liquid crystal display monitor 130. That is, the controller 135 of the digital camera 100 displays an image selected by the user on the liquid crystal display monitor 130 (S600).

FIG. 12 is a view showing a state where an image which is used for the smart phone 200 to identify an image is displayed on the liquid crystal display monitor 130 of the digital camera 100. By displaying on the liquid crystal display monitor 130 the image which is identified by the smart phone 200, it is possible for the user to visually grasp the image to be identified by the user.

On the other hand, the user operates the touch panel 210 of the smart phone 200 to activate application software (S610). That is, the controller 225 of the smart phone 200 activates application software in accordance with the user's operation. That application software is application software (hereinafter referred to as “image search application”) for searching for images recorded in the flash memory 245 in the smart phone 200 based on attribute information read by the smart phone 200 from the digital camera 100. By activating the image search application software, the smart phone 200 gets prepared for reading attribute information from the digital camera 100.

Subsequently, the user brings the digital camera 100 and the smart phone 200 into touch with each other (S620). By this touch operation, the NFC reader/writer 240 of the smart phone 200 reads, from the NFC tag 160 of the digital camera 100, an image identifier for identifying the image data being displayed on the liquid crystal display monitor 130 of the digital camera 100 as attribute information of the image data (S630). The image identifier is an identifier which is uniquely provided to image data when the image data is generated upon shooting. The image identifier is not changed even when the image data is copied or moved to another recording medium.

By referring to header information of the image data recorded in the flash memory 245, the controller 225 of the smart phone 200 checks whether or not an image having the same image identifier as the image identifier read in Step S630 exists in the flash memory 245. When the image having the same image identifier as the image identifier read in Step S630 exists in the flash memory 245, the controller 225 identifies the image (S640).
